No surprises.
It's deadly for Japanese player.
The way to make Allied opponent confused is :
1. If You want to send Your ships to a base and keep it in secret - set the destination for other base and the standoff range behind land based aircraft range. The Allies will surely strenghten the defense of that base. Then compose another TF (in the same hex) using ships in the first TF at sea so the enemy wouldn't see it from search planes. The only disadvantage is that there'll be no TF leader in this new one, but You can always change the HQ base to first TF and then move it to the new one. Sometimes works even better. Last - change the destination to the base You want to attack.
2. Confuse Allied leader by setting the TF destinations to variable bases which You'll never attack and setting accurate standoff range that Your TF's won't leave their ports. After few such actions he wouldn't trust SIGINT no more.
BTW
The AI needs to be strenghtened up. Last week I've managed to sink 95% of Japanese fleet loosing 1CV, 1CA and few DD's playing with help Japs in Coral Sea / Midway scenario. Japanese factories were bombed every week since mid 43 from Iwo Jima and Okinawa ...
Best Luck
